Abstract
Approaches to maintaining hard disk drive spindle motor rigidity and performance in low profile HDD devices comprise using an enclosure base with a bottom opening in which a separate motor cup is fitted and configured to support the spindle motor. The motor cup may then be fabricated using a different material than the enclosure base, such as a material having a higher modulus of elasticity than that of the base. Furthermore, a magnetic motor cup may be used to substitute for the thrust yoke typically used with conventional spindle motors.
